What is the maximum I can spend using Tap & Pay if you have an eligible Android phone with NFC?

If your transaction is over $100 you will be asked to enter your card pin on the terminal.

You can make up to 10 transactions without an internet connection. If you have exhausted your 10 uses, you will not be able to transact until you re-connect to the internet. This is something to be mindful of when you are transacting overseas.
